The actress recently saw an ad for the Korean film, which launched in the U.S. on May 29, and talked about the movie with her American colleagues and peers, according to local sports tabloids.

“Snowpiercer” is a sci-fi action film directed by Bong Joon-ho. The movie is based on the French graphic novel “Le Transperceneige” by Jacques Lob, Benjamin Legrand and Jean-Marc Rochette.

To the actress’ surprise, some of the crew members were not aware of the fact that the sci-fi film was a Korean movie, the reports added.

That weekend Kim invited about 10 crew members to the Los Angeles branch of CGV to watch the film. They reportedly praised both the movie and the director.

The actress is in Los Angeles for the filming of the second season of the U.S. television series “Mistresses” on ABC, in which she plays the psychiatrist Karen Kim. The show stars Kim, Alyssa Milano, Jes Macallan and Rochelle Aytes as the four lead characters.
